| definition |
- A mechanical device a) to provide the desired pressure for chemical and physical reactions, b) to control boiling points of fluids, as in gas separation, refrigeration, and evaporation, c) to evacuate enclosed volumes, d) to transport gases or vapors, e) to store compressible fluids as gases or liquids under pressure and assist in recovering them from storage or tank cars, and f) to convert mechanical energy to fluid energy for operating instruments, air agitation, fluidization, solid transport, blowcases, air tools, and motors.

| Abstract from DBPedia | A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. The main distinction is that the focus of a compressor is to change the density or volume of the fluid, which is mostly only achievable on gases. Gases are compressible, while liquids are relatively incompressible, so compressors are rarely used for liquids. The main action of a pump is to pressurize and transport liquids. Many compressors can be staged, that is, the fluid is compressed several times in steps or stages, to increase discharge pressure. Often, the second stage is physically smaller than the primary stage, to accommodate the already compressed gas without reducing its pressure. Each stage further compresses the gas and increases its pressure and also temperature (if inter cooling between stages is not used).圧縮機（あっしゅくき）とは羽根車若しくはロータの回転運動又はピストンの往復運動によって気体や液体などの流体を圧送する機械のことである。コンプレッサーともいう。有効吐出し圧力が200 kPa以下の圧縮機をブロワという。尚、改正前のJIS定義では圧力比によって送風機・圧縮機を分類していたが、ISOなどの国際規格との整合性を保つため2005年（平成17年）に改正された。これにより送風機扱いであったブロワが圧縮機となり、送風機とファンが同義となった。 (Source: http://dbpedia.org/resource/Compressor) |
